How Browser System Detection Works
Browser system detection uses JavaScript APIs to gather information about your device, OS, and capabilities. These APIs are designed with privacy in mind and return limited, sanitized data.
Key limitations:
- Memory caps at 8GB - Browsers limit reported RAM to protect privacy
- Architecture may be indeterminate - Modern browsers obscure CPU architecture for fingerprinting protection
- Approximate values - Some metrics like battery level are rounded
- Permission-gated - Certain info requires user consent (battery, media devices)
The tool uses APIs like navigator.hardwareConcurrency, screen, WebGL debug renderer, and Device Memory API to build a comprehensive system profile entirely in your browser.
Examples
GPU Renderer: NVIDIA GeForce RTX 3080
WebGL Version: 2.0
Max Texture Size: 16384pxDevice Memory: ≥8 GB
Logical CPU Cores: 12
Note: Browser caps at 8GBScreen Resolution: 2560 × 1440
Device Pixel Ratio: 2x
Actual Pixels: 5120 × 2880Frequently Asked Questions
Browsers cap the Device Memory API at 8GB to prevent fingerprinting and protect user privacy. If your device has 16GB+ RAM, the browser will only report 8GB.
By default, browsers hide GPU details. This tool uses the WebGL debug renderer extension to show your GPU, but this only works if your browser allows it. Many browsers now block this for privacy.
Modern Macs report "MacIntel" even on Apple Silicon chips due to Rosetta compatibility and browser privacy measures. The browser intentionally obscures whether you're using Intel or ARM.
Battery data is approximate and rounded by the browser. It's useful for debugging but not precise enough for critical applications. Some browsers (like Firefox) have disabled the Battery API entirely.
Click the "Copy as JSON" button to copy all system information in JSON format. You can paste this into bug reports or support tickets for developers to analyze.
💡 Tips
- Use "Copy as JSON" for bug reports—it includes all detected values in a structured format developers can analyze
- Memory and architecture may be obscured for privacy; use developer tools or native apps for exact specs
- Screen resolution shows CSS pixels; multiply by Device Pixel Ratio for actual physical pixels
- Battery API is deprecated in some browsers; if "Not supported" shows, your browser prioritizes privacy
